What will I learn?
This course offers a quick, hands-on way to master geometrical optics for correcting vision in everyday practice. You'll cover thin-lens basics, sign rules, and ray tracing, then use them for designing spectacles, calculating dioptres, adjusting vertex distance, and handling refractive errors. With straightforward examples and real clinical cases, you'll gain skills for precise calculations and confident explanations of lens options.
